Just looking at the documentation file, I have a couple of suggestions.

1). Make a note on the direction of gravity wrt the example image. Ie what
which axis/value will be positive with the device laid flat/stationary on
a desk. Might just prevent some confusion later.

2). Calibration, Accels and Gyros are noisy in different ways. Gyros tend
to be wrong in the long term, giving some consistant bias which should be
calibrated out. Accels are noisy in the short term, but generally right
over a long period.

Am I correct that the event framework will provide time-stamping of data,
thus making computation of relative movements possible.
